Add preliminary search field to users list
Fighting search with pagination. For some reason the serach function returns an array that pagination doesn't like. I can paginate the User class, or the PasswordRest class, but not the User.all array. Not sure how to paginate the searched users
Basic search implemented, but it's pretty lame so far
 Add search method to application helper and apply it to User model with respect to name and email with pagination
Add test for users search
Some refactoring and beautification of search form
